Description and Introduction

Level Shifting Low Offset Hot Swappable 2-Wire Bus Buffer with Stuck Bus Recovery The LTC4309CDE#PBF is a hot swappable 2-wire bus buffer manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** LINEAR (Linear Technology)  
- **Part Number:** LTC4309CDE#PBF  
- **Type:** Hot Swappable 2-Wire Bus Buffer  
- **Package:** DFN-8  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **I²C Bus Capacitance Buffering:** Isolates capacitance to allow more devices on the bus  
- **Rise Time Accelerators:** Improves signal integrity  
- **Low Quiescent Current:** Typically 1.5mA  
- **Operating Temperature Range:** 0°C to 70°C  
- **ESD Protection:** ±8kV HBM on SDA, SCL pins  

### **Descriptions:**  
The LTC4309CDE#PBF is designed to facilitate hot insertion into I²C and SMBus systems, preventing data corruption and bus lock-up. It provides bidirectional buffering, keeping the backplane isolated from live card insertion.  

### **Features:**  
- **Hot Swappable I²C and SMBus Buffer**  
- **Prevents Data Corruption During Board Insertion**  
- **Supports Clock Stretching and Multi-Master Arbitration**  
- **Compatible with I²C and SMBus Standards**  
- **Low Voltage Operation (2.7V to 5.5V)**  
- **Rise Time Accelerators for Improved Signal Integrity**  
- **High Noise Margin for Reliable Communication**  

This device is commonly used in applications requiring hot-swappable I²C/SMBus communication, such as servers, telecom equipment, and industrial systems.
